[0002] A heating furnace is a device used to heat materials to the required temperature. It is commonly used in processes such as metal heating treatment, glass melting, and welding. The furnace cover of a heating furnace is an important component of the heating furnace, which plays a role in sealing, heat insulation, and protection. The furnace cover is usually a component connected to the furnace body and can be opened or closed for easy operation and maintenance. However, most furnace covers currently require workers to open them manually, which is not convenient enough. In addition, the safety protection effect of existing furnace covers is relatively general. Once the furnace cover is accidentally opened, it is easy to cause harm to the surrounding workers.

As the limit plate slides, the rotating arm has two states: state one: when the limit plate slides to the rotating arm, the two limit blocks can respectively limit the rotation of the two rotating arms from both sides; state two: when the limit plate slides to the position where the rotating arm is removed, the restriction on the rotation of the two rotating arms is released; a second hydraulic cylinder, the second hydraulic cylinder is used to drive the limit plate to slide vertically.

[0005] In one embodiment, a mounting frame is further included, and the mounting frame is fixedly arranged beside the furnace body, and the first hydraulic cylinder and the second hydraulic cylinder are both arranged on the mounting frame.

[0006] In one embodiment, a first slide groove is vertically arranged on the mounting frame, and the top cover is vertically slidably connected to the first slide groove.

[0007] In one embodiment, a second slide groove is vertically arranged on the mounting frame, and the limiting plate is vertically slidably connected to the second slide groove.

[0008] In summary, in the present application, a lifting furnace cover of a heating furnace has the following beneficial effects compared with the prior art:

[0009] The first hydraulic cylinder is used to drive the top cover to open and close, which has a high degree of automation, reduces the labor of workers, and is more rapid and convenient;

[0017] See also Figure 1 , Figure 2 A lifting and lowering heating furnace cover comprises: a top cover 1, a first hydraulic cylinder 4, two rotating arms 5, a limiting plate 9, and a second hydraulic cylinder 11.

[0018] See also Figure 1 In one embodiment, the furnace body 3 is arranged vertically, and the top cover 1 is detachably arranged at the opening of the upper end of the furnace body 3, and a circle of high-temperature resistant sealing gasket 2 is fixed on the top cover 1 by conventional technical means (such as snap-fitting, embedding, etc.), which is used to provide a sealing effect between the two when the top cover 1 is closed on the furnace body 3.

[0019] See also Figure 1 The first hydraulic cylinder 4 is vertically downwardly arranged above the top cover 1, and the end of the telescopic rod thereof is fixedly connected to the top cover 1 by welding, so as to drive the top cover 1 to move vertically up and down to control the opening and closing of the top cover 1.

[0020] See also Figure 1 , Figure 2 Each of the rotating arms 5 includes a first straight arm 6 and a second straight arm 7. In each of the rotating arms 5, the first straight arm 6 and the second straight arm 7 are fixedly connected by an integral molding manner and are L-shaped. The two rotating arms 5 are respectively hinged to the opposite sides of the upper opening of the furnace body 3 through the first straight arm 6. The rotating axes of the two rotating arms 5 are both horizontal and parallel. When the top cover 1 is covered at the upper opening of the furnace body 3, the first straight arm 6 is rotated to a vertical state, and the second straight arm 7 will fit with the top surface of the top cover 1, and the end of the second straight arm 7 away from the first straight arm 6 extends upward in a direction parallel to the first straight arm 6 and is fixed with a protrusion 8.

[0021] See also Figure 1 , Figure 2, the limit plate 9 is in a horizontal state and slides vertically above the top cover 1, and the second hydraulic cylinder 11 is used to drive the limit plate 9 to slide vertically. The two opposite ends of the limit plate 9 are both extended downward and fixed with limit blocks 10. As the limit plate 9 slides, the rotating arm 5 has two states. State 1: When the limit plate 9 slides to the rotating arm 5, the side wall of the limit block 10 fits with the side wall of the protrusion 8, and the two limit blocks 10 can limit the rotation of the two rotating arms 5 from both sides respectively. State 2: When the limit plate 9 slides to the position where the rotating arm 5 is removed, the restriction on the rotation of the two rotating arms 5 is released. With this arrangement, when the top cover 1 is closed, the two rotating arms 5 are rotated to press them on the top cover 1, and then the two rotating arms 5 are limited by the limit plate 9, which can prevent the top cover 1 from opening accidentally, greatly improving its safety.

[0022] See also Figure 1 In one embodiment, it also includes a mounting frame 12, which is fixed to the side of the furnace body 3 by means of anchor bolts, and the cylinder bodies of the first hydraulic cylinder 4 and the second hydraulic cylinder 11 are fixed to the mounting frame 12 by welding. This arrangement has a more reasonable structure.

[0023] See also Figure 1 In one embodiment, a first slide groove 13 is vertically arranged on the mounting frame 12, and the cross-section of the first slide groove 13 is convex-shaped. A first slider 15 of a corresponding shape is fixedly provided on the top cover 1, and is vertically slidably connected to the first slide groove 13 through the first slider 15. This arrangement can support the sliding of the top cover 1, making the sliding effect more stable.

[0024] See also Figure 1 In one embodiment, a second slide groove 14 is vertically arranged on the mounting frame 12, and the cross-section of the second slide groove 14 is convex-shaped. A second slider 16 of a corresponding shape is fixedly provided on the limiting plate 9, and the limiting plate 9 is vertically slidably connected to the second slide groove 14 through the second slider 16. This arrangement can support the sliding of the limiting plate 9, making the sliding effect more stable.
